In the case of a high power AM radio transmitter with a tetrode as final stage tube (13), this final stage tube (13) is designed as a low voltage tetrode with a d.c. plate voltage <10 kV and an plate efficiency of >80%. By utilizing these measures, a compact transmitter design is achieved with virtually unchanged overall efficiency.
